IMPROVEMENT IN PLUIVIBERS PLUGS.

Speciiication forming part of Letters Patent No. 183,447, dated October 17, 1876; application filed August 12, 1876.

To all whom it may concern.-

description of thc same, reference being had f to the accompanying drawing, which forms part ot' this specification.

This invention relates to plumbers7 plugs for wash-basins, baths, sinks, and other purposes, and in which a removable stopper or plug proper is combined with a metallic plugseat. Heretofore said plug-seat or socket has been made of cast metal, and, in order to provide for a good fit ofl the plug or stopper within it, has required to be turned or ground, thereby involving much labor and no inconsiderable expense, besides necessitating the use of more metal than is requisite to resist pressure when in use, owing to the fact that to make a sound casting the metal requires to be of a given thickness.

This invention consists in a seat for plumbers7 plugs, struck up from sheet metal, as hereinafter described, the same forming a new article of manufacture heretofore unknown to the trade, and largely economizing labor by dispensing with all turning or grinding for reception ot'l the plug or stopper, besides saving metal and possessing other advantages over a cast-metal plug-seat.

Figure l represents a vertical section of a plumbers plug, applicable, for example, to earthenware wash-basins, and constructed in accordance with my invention. Fig. 2 is a like section of a like device, applicable, for instance, to baths or sinks.

In both forms of the plug-seat, as illustrated in the drawing, the flange or flanged head b is formed of one piece with the body 0L, being struck up from the same piece of sheet metal.

The stopper or plug proper f may also be struck up from sheet inet-al, or be of any other suitable material. The body d, in Fig. l, has a screw-thread upon it for securing the plugseat to its place by a nut-as, for instance, when the joint underl the ange b is a putty ene 5 but when said joint is a soldered one,

then the screw-thread on the body is dispensed with, as shown in Fig. 2. These differences are well understood by the trade.

In both forms of plug-seat, however, I pursue the same mode of construction. Thus, I rst cup up a piece of sheet metal into the form of a pipe; then anneal the latter to enable me to turn over, from one end of said pipe, the ange b, of a sufficient width to form a good joint, and so as to present a wide and easy tapering mouth for reception of the stopper or plug proper f. To do this with facility it is desirable to anneal the metal after the body d has been struck up. The iiange b is turned over, and the interior of the plugseat nished, as required, for a close and easy t of the plug f, without grinding or turning of the seat, by one and the same operation, which is a stamping one, using a simple die and punch for the purpose.

The outlet-apertures in the bottom of the body d may be made by drilling or otherwise.

The plug-seat thus constructed of sheet metal requires much less metal than when cast, and can be made with much less labor, as it requires no turning or grinding to form a proper seat for the plug 5 and its outside is also in a condition t0 be readily soldered in place, whereas, in the cast-metal seats, the outside has to be cleaned or turned off in order to be tted in place in the basin or other vessel, and soldered thereto. Moreover, the screwthreads, when necessary, may be stamped at the same operation by which the seat is formed, while in the cast-metal seats the screw-thread has to be cut, which is an expensive operation.

The plug employed may be cast and constructed in the ordinary manner, but is, preferably, stamped up similarly to the plugseat.

The abovementioned advantages all combine to render the plug-seat lnuch cheaper in construction than the ordinary castmetal plug-seat, and, on account of its lightness and thorough nish, is much superior thereto.

What I claim as my invention, and desire to secure by Letters Patent, as a new article of manufacture, is-

l. As an improved article of manufacture, sheet-metal plugsimlairly stamped, andadapta plnmbers plug-seat constructed of sheet ed to fit into said plug-seat, substantially as metal stamped into shape, with a flange, b, and for the purposes described.
